The structure of the filter mechanism is stabilized by the above arrangement, and the base 61 and the top cover 62 can be rotated in synchronization.
In the wastewater filtering system of the cleaning machine according to the embodiment, a bottom rotating ring 65 is rotatably arranged on the base 61; a top rotating ring 66 is rotatably arranged on the top cover 62; the porous layer 5 comprises a plurality of first stretchable mesh wires 53 and a plurality of second stretchable mesh wires 54; the first telescopic net wires 53 and the second telescopic net wires 54 are staggered, so that a filtering hole 55 is formed; one end of the first telescopic net wire 53 is arranged on the base 61; the other end of the first telescopic net wire 53 is arranged on a top rotating ring 66; one end of the second telescopic wire 54 is arranged on the top cover 62; the other end of the second telescopic wire 54 is provided to a bottom rotating ring 65.
Specifically, since the first telescopic wire 53 and the second telescopic wire 54 are fixed at one end to the base 61 or the top cover 62, the other end is fixed to the top rotating ring 66 or the bottom rotating ring 65, and the top rotating ring 66 or the bottom rotating ring 65 is rotatable with respect to the base 61 or the top cover 62; therefore, when the aperture of the filtering holes 55 of the porous layer 5 needs to be changed, only the top rotating ring 66 or the bottom rotating ring 65 needs to be rotated, so that the included angles between the first telescopic net wires 53 and the second telescopic net wires 54 and the horizontal plane are changed, and further the grid interval (i.e. the aperture of the filtering holes 55) formed by the first telescopic net wires 53 and the second telescopic net wires 54 is changed, so as to obtain different interception capacities and improve filtering flexibility.
In the wastewater filtering system of the cleaning machine according to the embodiment, the base 61 and the top cover 62 are provided with guide grooves 7; a sliding block 71 is arranged in the guide groove 7 in a sliding way; a spring 72 abutted against the sliding block 71 is arranged at one end of the guide groove 7 close to the shell 41;

In the wastewater filtering system of the cleaning machine according to the embodiment, the first cavity 51 is provided with a steam nozzle 81 and a flushing nozzle 82; the steam nozzle 81 and the flushing nozzle 82 are each provided with nozzles facing the porous layer 5. In the wastewater filtering system of the cleaning machine according to the embodiment, a rotating shaft 83 connected with the base 61 is disposed in the first cavity 51; the rotating shaft 83 is provided with a plurality of rotors 84; the shell 41 is provided with a first electromagnetic valve 45 at a first discharging hole 43; the housing 41 is provided with a second solenoid valve 46 at the second outlet 44.
Specifically, when in operation, wastewater generated by the cleaning machine is discharged into the first treatment device 1, and is adsorbed under the action of surface tension and the surface of micro-bubbles generated by the aeration pipe 12 is brought to the surface of liquid for enrichment, so as to form a first enrichment; at this time, the second electromagnetic valve 46 is closed, and the first electromagnetic valve 45 is opened; as the liquid level rises, the first concentrate flows into the first cavity 51 of the separation filter 4 through the first overflow pipe 13, and as the filtering mechanism in the separation filter 4 is in a rotating state, the first concentrate entering the first filter impacts the surface of the porous layer 5 under the action of centrifugal force generated by the rotor 84, saponified material particles with the diameter larger than the pore diameter of the filtering holes 55 of the porous layer 5 are trapped inside the porous layer 5 to form second concentrate, and saponified material particles with the diameter smaller than the pore diameter of the filtering holes 55 of the porous layer 5 penetrate through the porous layer 5 to enter the second cavity 52 between the shell 41 and the porous layer 5 to form filtrate; the filtered liquid of the second cavity 52 flows into the second treatment device 2 through the first discharge hole 43, a third enrichment substance is formed at the sedimentation part of the second treatment device 2 and is conveyed into the belt filter press 3 to be concentrated to form waste residues, and supernatant liquid of the second treatment device 2 can flow back to the cleaning machine from the second overflow pipe 23 for reuse;
when the second concentrate is required to be discharged from the first cavity 51 of the separation filter 4, the second electromagnetic valve 46 is opened, the first electromagnetic valve 45 is closed, and the rotating speed of the motor 64 is increased, so that the aperture of the filtering holes 55 of the porous layer 5 is enlarged, and the steam spray pipe 81 sprays high-temperature steam to the porous layer 5 to soften saponified material particles trapped on the surface of the porous layer 5, so that the saponified material particles are more beneficial to reaching the second cavity 52 through the inside of the porous layer 5; as the rotational speed increases, the centrifugal force to which the saponified material particles themselves are subjected increases, making it easier for them to pass through the porous layer 5 into the second cavity 52; after the rotation speed is increased, the sliding block 71 drives the bottom rotating ring 65 and the top rotating ring 66 to further rotate, so that the tension applied to the first telescopic net wire 53 and the second telescopic net wire 54 is increased, the wire diameter of the first telescopic net wire is further contracted, and the diameter of the filtering holes 55 of the porous layer 5 is further enlarged, so that saponified material particles can more easily pass through the inside of the porous layer 5 to the second cavity 52; meanwhile, after the second concentrate is discharged, the flushing spray pipe 82 sprays water to the surface of the porous layer 5 to clean the porous layer 5, at this time, the rotation speed of the motor 64 is reduced, the first telescopic net wire 53 and the second telescopic net wire 54 in a stretched state shrink, the surface area is reduced, so that the saponified material particles remained on the surface of the porous layer are synchronously enriched, and the adhesive force between the saponified material particles and the first telescopic net wire 53 and the second telescopic net wire 54 is synchronously reduced due to the reduction of the effective contact area, so that the cleaning liquid flow is easier to flush the saponified material particles away from the surfaces of the first telescopic net wire 53 and the second telescopic net wire 54, and the cleaning effect is better; at the same time, the saponified material particles attached to the surface of the shell 41 are washed and discharged to the belt filter press 3 through the second discharge port 44 to be further concentrated to obtain waste residues.
